Description

Paper base material printing method and paper base material manufacturing apparatus

The present invention relates to a paper substrate printing method and a paper substrate printing apparatus.

The present invention also relates to a paper substrate manufacturing method and manufacturing apparatus, and more particularly to a technique suitable for use in manufacturing a paper container corresponding to a large variety of small lots.
This application claims priority based on Japanese Patent Application No. 2014-225568 filed in Japan on November 5, 2014 and Japanese Patent Application No. 2014-225571 filed in Japan on November 5, 2014, The contents are incorporated herein.

2. Description of the Related Art Conventionally, a stored item is stored in a plurality of types of paper containers (paper base materials) having different designs while being the same product (see, for example, Patent Document 1). The paper containers in which the stored items are stored are made to flow through the distribution channel, and are sold at the store.
In the case of a paper container on which a picture is printed so that a trading card, a collection card or the like can be obtained by cutting out a part of the paper container, it is necessary to flow the paper container having a different pattern as a set product to the distribution channel. The paper container is generally manufactured by a printing company.

A manufacturing method of a set product in such a paper container is as follows, for example. In the first step, printing is performed on a large paper container paper (paper base material) using a printing plate with multiple imprints of blanks.
Next, in the second step, large-sized paper container paper on which multi-sided printing has been performed is punched into blanks by a punching machine. After the punching, the blank paper sheets are cut into individual blanks and stacked. The same pattern (fixed printing content) is printed on the blanks stacked at this time. In this specification, a blank refers to a developed paper container before two predetermined sides are glued (sucked). Further, the blank state represents a state of the developed paper container before two predetermined sides are glued (sucked).

Next, in the third step, on the blanks on which the same pattern is printed, a pattern corresponding to a different paper container collected as a paper container set, that is, a variable pattern (variable printing content) is printed in the order of collection. Blanks on which the variable pattern is printed are stacked in the printed order. An ink jet printer using UV (ultraviolet) curable ink can be used for printing the variable pattern. The blanks on which the variable pattern is printed by the ink jet printer are irradiated with UV to cure the ink.

Next, in the fourth step, sack pasting is performed in which the two blanks are glued, folded and laminated, and the blanks are processed into a cylindrical shape.
Next, in the fifth step, packing is performed so that the stacking order of the sack-attached blanks does not change, and it is shipped from the printing company to the manufacturer.

Also, in the paper container (paper box) that stores parts of many types, such as automobile parts packages, the product number, barcode, lot number, etc. for recognizing the stored parts are stored for each type / lot. Different information is expressed by a bar code or the like, and this bar code or the like is printed as variable information on the outer surface of the paper box. Also, on the outer surface of the paper container, it is possible to visually check the package design, company name, product name, image on the contents, precautions for use, and information obtained by digitizing or designing them on the parts other than variable information. Characters and designs are printed as fixed information of the product.

In the manufacture of paper containers, fixed information such as package design and company information can be printed at the manufacturing stage of material paper for producing paper containers. On the other hand, variable information such as shipping date, expiry date, lot number, etc. that can be changed every day cannot be printed at the manufacturing stage of the material paper, so a thermal printer, an ink jet printer, a laser, etc. immediately before storing the contents in the paper container. Printing is performed directly on the surface of the paper container using a printing machine or the like.

There are many combinations of such part numbers, barcodes, lot numbers, etc., and when manufacturing paper containers corresponding to many types of small lots, it is necessary to print for each variable information. Management of plates and prevention of confusion between different varieties are problems.
As a means for solving this problem, as shown in Patent Document 1, a method for manufacturing a paper container set is described in which a process of printing variable information is sequentially performed after a process of printing fixed information on a material paper serving as a paper container. .

Japanese Unexamined Patent Publication No. 2005-41116

However, a product number, a bar code, a lot number, etc. for recognizing a variable pattern, particularly a stored item such as a component stored in a blank, in an inkjet printer using a UV curable ink disclosed in Patent Document 1. When printing, the printed part becomes faint and looks bad. On the other hand, if a variable pattern is printed so as to improve the appearance, light may be reflected on the ink, so that the variable pattern may not be recognized by a reader such as a barcode reader. *

Further, when manufacturing a small-lot multi-variety paper container, variable information, in particular, a product number for recognizing a part, a barcode, a lot number, etc. is printed on the blank paper container after punching. However, the blank paper container after punching has a complicated outline shape, and it has been difficult to store the paper container neatly after printing.
In addition, the blank paper containers after printing the variable information overlap in the order of the serial numbers of the variable information such as the product number, barcode, lot number, etc. The stacking order will be shifted. For this reason, there is a problem in use in automating the part number management and lot number management of automobile parts.
Further, when the printed variable information is inspected using an inspection machine, there is a problem that the inspection cannot be performed if the paper container is displaced.

The present invention has been made in view of such problems, and when printing variable print contents such as a product number, a barcode, and a lot number for recognizing stored items, the printed part becomes clear, An object of the present invention is to provide a paper base material printing method and a paper base material manufacturing apparatus in which errors in recognizing the type of stored items by a bar code reader or an inspection machine are reduced.

Further, the present invention provides a paper container that can be printed so that variable information such as a product number, a barcode, and a lot number for recognizing parts does not differ from the stacking order of the paper container in a paper container on which variable information is printed. The purpose is to provide a manufacturing apparatus.

In order to solve the above problems, the present invention proposes the following means.
The printing method of the paper base according to the first aspect of the present invention includes a first variable printing step of printing the first variable printing content on the first paper base on which the fixed printing content is printed by the laser printing unit,

In the second aspect, the first variable print content may include authentic print content for determining authenticity of the first paper substrate.
The paper base material manufacturing apparatus according to the second aspect includes the first paper base material on which the first variable printing content is printed and the second paper base material on which the second variable printing content is printed in a first direction. A discharge mechanism for discharging, and a discharge tray portion that is disposed below the discharge mechanism and supports the first paper substrate and the second paper substrate discharged from the discharge mechanism on the upper surface side. A discharge roller unit that moves the first paper base on which the first variable printing content is printed and the second paper base on which the second variable printing content is printed in the first direction. A guide portion that is positioned downstream of the discharge roller portion and that is fed to the discharge tray portion, wherein the guide portion is configured to discharge the first paper base material and the second paper sheet discharged from the discharge roller portion. A support portion for supporting an end portion of the paper base material in a second direction orthogonal to the first direction; The first paper base material and the second paper base material that move in the first direction in contact with the end portions in the second direction of the first paper base material and the second paper base material discharged from the discharge roller portion And a posture control unit that adjusts the paper base material to have a predetermined posture. As a result, the paper base material supported by the support portion does not come into contact with the paper base material placed on the paper discharge tray portion, and the paper base material placed on the paper discharge tray portion is pushed away. In this case, the variable information can be successively placed on the paper discharge tray unit in the same stacking order as the printing order.

Said 2nd aspect WHEREIN: The said support part has a support piece extended in the said 1st direction (movement direction), and the said support piece is said 1st of said 1st paper base material and said 2nd paper base material. You may arrange | position in the position near the said edge part in 2 directions (width direction). As a result, the paper base is transported to the paper discharge tray while being supported at the end in the width direction, so that the central part in the width direction of the paper base is lowered by its own weight, and the cross section in the width direction of the paper base is convex downward. The paper base material supported by the support part is placed on the paper discharge tray part so that the tip of the paper base material does not hang downward and can move on the support part. Will not abut.

In the second aspect, the support piece may be disposed at a position close to both ends of the first paper base and the second paper base in the second direction.

The paper base material supported by the support part is placed on the paper discharge tray part so that the tip of the paper base material does not hang downward and can move on the support part. Will not abut.

In the second aspect, while the first paper base is fed in a state of being supported by the support piece, the first direction tip of the first paper base is in the discharge tray part. The height of the support piece from the discharge tray portion at the downstream end in the first direction may be set so as to maintain a state in which the support is not in contact with the placed paper base material. As a result, the paper base is supported at the end position in the width direction, and the cross section in the width direction of the paper base becomes a substantially arcuate shape protruding downward, so that the front end of the paper base does not hang down by the support portion. The supported paper base material does not come into contact with the paper base material placed on the paper discharge tray section.
Here, the height of the support piece can be set to a predetermined state in accordance with the thickness of the paper base and the dimension of the paper base in the moving direction.

In the second aspect, the height of the posture control unit may be set to be higher than the upper end of the support piece in the entire length in the first direction. As a result, the side end of the paper substrate that moves on the support piece can move while contacting the posture control unit, so that the moving paper substrate is inclined with respect to the moving direction. Can be prevented.

In the second aspect, the posture control unit may have the same length as the support piece in the first direction. As a result, the side end of the paper substrate that moves on the support piece can move while contacting the posture control unit, so that the moving paper substrate is inclined with respect to the moving direction. Can be prevented.

In the second aspect, an inspection unit for inspecting a printing state of the first variable printing content may be provided for the first paper base placed on the discharge tray unit. As a result, the paper base material can be overlapped so that the variable information printed within the inspection object range by the inspection unit can be positioned, so that the paper base material discharged by the discharge mechanism can be inspected as it is.

In the second aspect, the first paper base and the second paper base have a wide part having a width dimension that can be supported by the support piece, and a narrow part having a width dimension that is not supported by the support piece; The first paper base and the second paper base may be moved such that the wide part is positioned in front of the first direction with respect to the narrow part. Thus, by supporting the wide portion by the support portion, it becomes possible to print the variable information while accurately setting the order and the overlapping position of the paper base materials.

In the second aspect, the first paper base and the second paper base before being sent to the laser printing unit are sheet material sheets, or the material sheets are folded from a folding line. It may be in a state where a sack is applied so as to form a cylinder. Thereby, it can respond to any paper base material.

According to each aspect of the present invention, when printing variable print contents such as a product number, a barcode, and a lot number for recognizing a stored item, the printed portion becomes clear and stored by a barcode reader, an inspection machine, or the like. It is possible to reduce recognition errors of object types.

According to each aspect of the present invention, the printed paper base material is prevented from being pushed away from the paper base material placed on the paper discharge tray portion, and the variable information is printed in the same order as the printed order. The paper bases thus stacked are successively stacked and placed on the paper discharge tray. In addition, it is possible to accurately set the stacking order and the stacking position of the paper base materials, and to inspect the paper base materials discharged by the discharge mechanism as they are.

As the roll paper, white board paper such as a white ball or yellow board paper is used. For printing on roll paper, a known printing method such as gravure printing or offset printing can be suitably used.

In the paper substrate 100, a small side plate 101, a bottom plate 102, a small side plate 103, and a top plate 104 are connected in this order in the longitudinal direction X along the long side 102 a of the rectangular bottom plate 102.
On both sides of the short side direction Y along the short side 102b of the bottom plate 102 in the small side plate 101, flap plates 106 are provided continuously. Flap plates 107 are provided on both sides of the small side plate 103 in the short direction Y. A flap plate 108 is connected to the side opposite to the side of the top plate 104 to which the small side plate 103 is connected.

Large side plates 110 and 111 are provided on both sides of the bottom plate 102 in the short direction Y. A flap plate 112 is connected to the side opposite to the side where the bottom plate 102 of the large side plate 110 is connected. A flap plate 113 is connected to the side opposite to the side where the bottom plate 102 of the large side plate 111 is connected.
Between the small side plate 101 and the bottom plate 102, a crease having a reference numeral omitted is formed. By using this fold as a hinge, the small side plate 101 can be easily bent with respect to the bottom plate 102.
The small side plate 103, the top plate 104, and the large side plates 110 and 111 are printed with fixed patterns (fixed printing contents) 103a, 104a, 110a, and 111a (hereinafter referred to as fixed patterns 103a and the like). The fixed pattern 103a and the like represent the package design of the paper substrate 100.

The small side plate 101, the bottom plate 102, and the small side plate 103 are areas where the fixed pattern 103a or the like is not printed, and include first variable print contents (variable print contents) 131 and second variable print contents (described later). Print areas 101a, 102c, and 103b for printing variable print content) 132 and third variable print content (variable print content) 133 are provided.

In this example, the fixed pattern 103a and the like include the name of the stored items stored in the paper base material 100 after the paper base material 100 is assembled, the name of the manufacturer that uses the stored items, and the picture representing the stored items. It is. However, the contents described in the fixed pattern 103a and the like are not limited to this, and can be selected as appropriate.

Next, the laser printing unit 10 will be described.
As shown in FIG. 1, the laser printing unit 10 includes a photosensitive drum 11, a charging unit 12 for charging the surface of the photosensitive drum 11 with negative static electricity, and a laser oscillator 13a for exposing the charged photosensitive drum 11. A developing unit 14 for attaching the toner T to the photosensitive drum 11, a transfer unit 15 for transferring the toner T attached to the photosensitive drum 11 to the paper substrate 100, and the paper substrate 100. A fixing unit 16 for fixing the toner T and a control unit 17 for controlling the charging unit 12 and the like.

The photosensitive drum 11 is supported in the case 25 so as to be rotatable around the axis C of the photosensitive drum 11. In the developing unit 14, the toner T is agitated.
The fixing unit 16 fixes the toner T to the paper substrate 100 by applying heat or pressure to the paper substrate 100, for example.
In the case 25, there are provided a roller 19 for conveying the paper substrate 100 and a roller drive motor (not shown) for rotating the roller 19.

The control unit 17 is connected to and controls the charging unit 12, the exposure unit 13, the developing unit 14, the transfer unit 15, the fixing unit 16, and the roller drive motor.
The control unit 17 has an arithmetic element and a memory (not shown). The memory stores a control program, a first variable printing content 131, a second variable printing content 132, and a third variable printing content 133 shown in FIG.
The first variable printing content 131 is used to determine the character (number) 131a representing the lot number of the stored item stored in the paper base 100, the bar code 131b representing the lot number, and the authenticity of the paper base 100. It includes a security symbol (authentication symbol) 131c which is the authentic print content.

The barcode 131b code is a representation of information converted to improve the efficiency and confidentiality of information transmission, such as a barcode and QR code (registered trademark). Means information whose contents cannot be easily understood. The bar code 131b is read by a known bar code reader (reading device) (not shown), so that the bar code reader reads the stored item information that is information about the stored item represented by the bar code 131b. The stored item information is, for example, the name or product number of the stored item. These characters 131a and barcode 131b are provided for recognizing the stored items stored in the paper base material 100 on which the first variable print content 131 is printed.
By printing the security symbol 131c on the paper base material 100, it can be seen that the paper base material 100 is not a fake (fake) but a real (true).

The second variable print content 132 and the third variable print content 133 are configured in the same manner as the first variable print content 131. That is, the second variable print content 132 includes characters 132a, a bar code 132b, and a security symbol 132c. The third variable print content 133 includes characters 133a, a bar code 133b, and a security symbol 133c.
However, the first variable print content 131, the second variable print content 132, and the third variable print content 133 are different from each other. More specifically, the character (first character) 131a, the character (second character) 132a, and the character (third character) 133a are different from each other, and the barcode (first barcode) 131b, the barcode The (second barcode) 132b and the barcode (third barcode) 133b are different from each other.

In this example, the security symbol 131c, the security symbol 132c, and the security symbol 133c are different from each other, but they may be the same. In the present embodiment, the security symbols 131c, 132c, and 133c have the same shape and are changed in direction so that it can be easily understood that the security symbols 131c, 132c, and 133c are authentic print contents.

As described in detail later, the laser printing unit 10 configured as described above includes a plurality of paper base materials (first paper base material, second paper base material, third paper base material) on which a fixed pattern 103a or the like is printed. ) 100 can be printed with variable print contents 131, 132, 133, respectively.

The case 25 can be formed of a steel plate, resin, or the like. The case 25 has openings 25a and 25b shown in FIG.
The paper feed tray 30 is attached to the case 25 so that the lower end portion of the paper feed tray 30 is positioned below the opening 25a. The paper discharge tray 35 is attached to the case 25 so that the lower end portion of the paper discharge tray 35 is positioned below the opening 25b.

Next, a printing method (hereinafter also abbreviated as a printing method) of the paper substrate 100 of the present embodiment using the printing apparatus (paper substrate manufacturing apparatus) 1 configured as described above will be described. FIG. 4 is a flowchart showing the printing method of this embodiment.
First, in step S1 shown in FIG. 4, a fixed pattern 103a or the like is printed on a large roll paper (not shown) by gravure printing or the like.
In step S2, a plurality of paper base materials 100 are punched by a punching machine from a roll paper or the like on which a fixed pattern 103a or the like is printed. A plurality of punched paper substrates 100 are arranged on the paper feed tray 30 of the printing apparatus 1 shown in FIG. At this time, the plurality of paper base materials 100 are arranged in a state of being stacked in the thickness direction of the paper base material 100.

In the first variable printing step (variable printing step, one variable printing step) in step S3 (hereinafter also referred to as first variable printing step S3), a paper substrate (first paper base) on which the fixed pattern 103a or the like is printed The first variable printing content 131 is printed on the material 100 by the laser printing unit 10. That is, printing is performed on a paper substrate (paper substrate before processing) 100 in a blank state.
Specifically, the control unit 17 causes the charging unit 12 to charge the surface of the photosensitive drum 11 with negative static electricity. The photosensitive drum 11 is rotated in the direction D around the axis C by a drum drive motor (not shown).
The exposure unit 13 irradiates the photosensitive drum 11 with laser light L from the laser oscillator 13a. The portion of the surface of the photosensitive drum 11 irradiated with the laser light L is free from negative static electricity. For this reason, the surface of the photosensitive drum 11 is irradiated with the laser light L in a shape representing the first variable print content 131.

The toner T in the developing unit 14 is brought close to the photosensitive drum 11. Then, the toner T adheres only to the portion where the negative static electricity on the surface of the photosensitive drum 11 is eliminated. The paper base 100 placed on the paper feed tray 30 is conveyed by the roller 19, and the paper base 100 is brought into close contact with the photosensitive drum 11.
The transfer unit 15 gives a positive charge from the opposite side of the paper base 100 to the photosensitive drum 11. The toner T adhering to the surface of the photosensitive drum 11 moves to the paper substrate 100.
By applying heat or pressure to the paper substrate 100 or the like by the fixing unit 16, the toner T transferred to the paper substrate 100 is fixed to the paper substrate 100.

Through the first variable printing step S3 described above, the first variable printing content 131 is printed in the printing areas 101a, 102c, and 103b of the paper substrate 100 as shown in FIG. In this example, the characters 131a and the barcode 131b of the first variable print content 131 are printed in the print areas 101a, 102c, and 103b. A security symbol 131c is printed at the corner of the print area 102c. In this way, the characters 131a, barcode 131b, and security symbol 131c of the first variable print content 131 are printed simultaneously.
Since the first variable printing content 131 is fixed on the paper substrate 100 by heating the toner T or the like, even if it is rubbed, it is difficult to fade.
Printing the first variable print content 131 with the laser printing unit 10 makes the print portion of the first variable print content 131 clearer than when the first variable print content 131 is printed with an inkjet printer.

As shown in FIG. 1, the paper base material (paper base material after processing) 100 on which the first variable print content 131 is printed is stacked on the paper discharge tray 35 in the thickness direction together with other paper base materials 100. Arranged in a state.
Note that the number of paper base materials 100 on which the first variable printing content 131 is printed in the first variable printing step S3 may be one or two or more.

Similarly, in the second variable printing step (variable printing step, another variable printing step) (hereinafter also referred to as second variable printing step S4) in step S4, the fixed pattern 103a is printed as shown in FIG. The second variable printing content 132 is printed by the laser printing unit 10 on the paper base (second paper base) 100 that has been made. The characters 132a, barcode 132b, and security symbol 132c of the second variable printing content 132 are printed simultaneously.
In the third variable printing step (variable printing step) (hereinafter also referred to as third variable printing step S5) in step S5, a paper base material (third paper base material) on which the fixed pattern 103a is printed as shown in FIG. ) The third variable printing content 133 is printed at 100 by the laser printing unit 10. The characters 133a, barcode 133b, and security symbol 133c of the third variable printing content 133 are printed simultaneously.
Thus, the variable printing process is performed three times in total by performing the first variable printing process S3, the second variable printing process S4, and the third variable printing process S5, respectively.

Note that the number of the paper bases 100 on which the second variable printing content 132 and the third variable printing content 133 are printed in the second variable printing step S4 and the third variable printing step S5 may be one or two or more, respectively. Good.
First variable printing content 131 printed on the paper base material 100 in the first variable printing step S3, second variable printing content 132 printed on the paper base material 100 in the second variable printing step S4, and third variable printing The third variable print content 133 printed on the paper substrate 100 in step S5 is different from each other.
The printing method of this embodiment is completed in the above steps S1 to S5.

The printed paper base material 100 is assembled as a box-shaped paper container with the top plate 104 opened by bending at a fold and gluing the flap plate 106 and the like. The stored item is stored in the paper container, and the flap plate 108 is glued to the small side plate 101 to complete the stored paper container.
For example, this paper container with stored items can be suitably used when parts such as automobiles and electrical products are delivered to manufacturers of finished products such as automobiles and electrical products.

As described above, according to the printing apparatus 1 and the printing method of the present embodiment, printing is performed on the paper substrate 100 by the laser printing unit 10. Since the printing by the laser printing unit 10 is fixed to the paper substrate 100 by heating the toner T or the like, the printed portion of the first variable printing content 131 becomes clear. Therefore, it is possible to reduce recognition errors of the type of stored items when reading the first variable print content 131 with a barcode reader or the like.
At this time, the first variable printing content 131 printed on the paper substrate 100 in the first variable printing step S3, the second variable printing content 132 printed on the paper substrate 100 in the second variable printing step S4, The laser printing unit 10 can perform printing so that the third variable printing content 133 printed on the paper substrate 100 in the third variable printing step S5 is different from each other.

By including the security symbol 131c in the first variable print content 131, the content of the security symbol 131c can be changed for each desired number of sheets of the paper substrate 100. Thereby, it is possible to prevent the security symbol 131c from being imitated in a counterfeit (paperware) of a paper container formed by assembling the paper base material 100.
By including the security symbol 131c in the first variable print content 131, it is possible to easily change the content of the security symbol 131c and the location where the security symbol 131c is printed.

The bar code 131b of the first variable printing content 131 is a bar code reader that can read the contents information represented by the bar code 131b. Since the first variable print content 131 is not easily faded, the barcode 131b can be reliably read by the barcode reader.
The variable printing contents 131, 132, and 133 whose printing contents change depending on the paper base material 100 are printed by the laser printing unit 10, so that the number of plate making can be reduced and the manufacture of various types of paper base materials 100 is easy. Become.

By using the laser printing unit 10 using the laser light L instead of the ink jet printer for printing on the paper base material 100, it is possible to increase the resolution when printing the first variable print content 131 as compared with the ink jet printer.

Although one embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and includes modifications, combinations, deletions, and the like within a scope that does not depart from the gist of the present invention. It is.
For example, in the embodiment, the case where the fixed print content is the fixed pattern 103a or the like has been described. However, the fixed printing content may be characters, graphics, or the like, or may be content that combines a pattern, characters, graphics, or the like.
The case where the authentic print content is the security symbol 131c has been described. However, the authentic print content may be a genuine character that is a character, a true graphic that is a graphic, or a content that is a combination of a symbol, a character, and a graphic.

The first variable printing content 131 may be one of the character 131a and the barcode 131b. Although the case where the first variable print content 131 includes the security symbol 131c has been described, the first variable print content 131 may not include the security symbol 131c.

In the embodiment, the case where the characters 131a, the characters 132a, and the characters 133a are different from each other and the barcode 131b, the barcode 132b, and the barcode 133b are different from each other has been described. However, the character 131a, the character 132a, and the character 133a may be the same, or the barcode 131b, the barcode 132b, and the barcode 133b may be the same. This is because even with this configuration, the first variable print content 131, the second variable print content 132, and the third variable print content 133 are different from each other.
The case where the variable print contents are the first variable print contents 131, the second variable print contents 132, and the third variable print contents 133 that are different from each other has been described. However, the variable print content is not limited to this, and may be two different types of content, or may be four or more types of content different from each other.

For example, when the variable printing contents are two kinds of contents different from each other, the two kinds of variable printing contents are printed on the paper substrate 100 by the laser printing unit 10. In the printing method for the paper substrate 100 described above, the third variable printing step S5 is not performed.
On the other hand, when the variable printing contents are four kinds of contents different from each other, the four kinds of variable printing contents are printed on the paper base material 100 by the laser printing unit 10. In the printing method for the paper base material 100 described above, the fourth variable printing content is printed by the laser printing unit 10 on the paper base material 100 on which the fixed pattern 103a is printed after the third variable printing step S5. This fourth variable print content is different from the variable print content 131, 132, 133.

Although the case where variable printing content is printed on the blank paper substrate 100 by the laser printing unit 10 has been described, printing may be performed with the paper substrate 100 being sack-attached. When the number of lots is large, the variable printing content may be printed by the laser printing unit 10 on a paper base in a large roll paper state.

It has a barcode reader 262 and a control unit (not shown) that can determine these detection results.

Hereinafter, a paper container manufacturing method by the paper container manufacturing apparatus according to the present embodiment will be described.
FIG. 11A to FIG. 11C are schematic plan views showing a discharging process in the discharging mechanism 250 in the present embodiment.

As a manufacture of the paper container in the present embodiment, first, a predetermined material sheet of a sheet is prepared in a fixed information printing step, and a design area (fixed information area) 2D is printed on the material sheet, and necessary folding lines, etc. Engrave. Thereafter, in the die cutting process, the paper container on which the design region 2D is printed is punched into a predetermined contour shape and punched to obtain a paper container (paper container before processing) 2B in a blank state, as shown in FIG. It is stored in the stocker 221 in a state.

Next, in the variable information printing step, first, the paper container 2B is sent from the stocker 221 of the paper container supply section 220 to the section variable information printing section 212 by the supply rollers 222a and 222b.

In the variable information printing unit 212, the variable information region 2R is printed by the printing unit 240 on the paper container 2B.
Specifically, the control unit 247 causes the charging unit 242 to charge the surface of the photosensitive drum 241 with negative static electricity. The photosensitive drum 241 is rotated in the direction D around the axis C by a drum drive motor (not shown).
The exposure unit 243 irradiates the photosensitive drum 241 with the laser light L from the laser oscillator 243a. The portion of the surface of the photosensitive drum 241 irradiated with the laser light L is free of negative static electricity. For this reason, the surface of the photosensitive drum 241 is irradiated with the laser light L in a shape representing the contents of variable information.

The toner T in the developing unit 244 is brought close to the photosensitive drum 241. Then, the toner T adheres only to the portion where the negative static electricity on the surface of the photosensitive drum 241 disappears. The paper unit 2B supplied from the paper unit supply unit 220 is conveyed by the rollers 231a, 231b, and 231c, and the paper unit 2B is brought into close contact with the photosensitive drum 241.
The transfer unit 245 applies a positive charge from the side opposite to the photosensitive drum 241 in the paper container 2B. The toner T adhering to the surface of the photosensitive drum 241 moves to the paper container 2B.
By applying heat or pressure to the paper container 2B or the like by the fixing unit 246, the toner T transferred to the paper container 2B is fixed to the paper container 2B.

The paper container 2B on which the variable information is printed moves in the movement direction M, and when the leading end 2B1 reaches the discharge roller portion 251a, the paper container 2B moves in the movement direction M by the discharge roller portion 251a, and as shown in FIG. It is discharged from 254b.

Next, the paper container 2B is further moved in the movement direction M by the discharge roller portion 251a, and as shown in FIG. 11B, both ends of the wide portion 2Ba in the width direction V are supported by the support pieces 253 and 253 of the guide portion 254. It becomes a state. At this time, the paper container 2 </ b> B moves in the movement direction M in a state where the end of the wide portion 2 </ b> Ba in the width direction V is in contact with the attitude control unit 252 of the guide portion 254. This prevents the paper container 2B from being inclined with respect to the movement direction M.
In this state, the paper container 2B abuts on the support pieces 253 and 253 at both ends in the width direction V of the wide portion 2Ba, and the weight of the paper container 2B is supported by the portions in contact with the support pieces 253 and 253. For this reason, the central position in the width direction V of the paper container 2B is slightly lowered, and the cross-sectional shape along the width direction V is a downwardly convex arc shape.

In addition, since the height of the support pieces 253 and 253 is set as described above, the front end 2B1 of the paper container 2B is placed in the paper discharge tray unit 255 and the previous process placed on the paper discharge tray unit 255. It does not contact the processed paper container 2B.

Next, the paper container 2B is further moved in the movement direction M by the discharge roller portion 251a. As shown in FIG. 11C, the paper container 2B has the movement direction M of the wide portion 2Ba in the movement direction of the support pieces 253 and 253. It will be in the state located in the downstream rather than a downstream edge part. In this state, the wide section 2Ba of the paper container 2B is not supported by the paper container 2B support piece 253, and is dropped and placed on the paper discharge tray section 255. At this time, in the state where the most downstream end in the moving direction M of the narrow portion 2Bb of the paper container 2B is discharged from the discharge port 254b by the discharge roller portion 251a, in the width direction V, between the support piece 253 and the support piece 253. It is positioned and placed on the support plate 254a. That is, the wide part 2Ba of the first paper base and the second paper base has a width that can be supported by the support pieces 253 and 253, and the narrow part 2Bb has a width that is not supported by the support pieces 253 and 253. . Further, the first paper base and the second paper base are moved so that the wide portion 2Ba is positioned in front of the first direction rather than the narrow portion 2Bb.

As described above, the paper container 2B is discharged to the paper discharge tray section 255 while being supported by the guide section 254, so that the paper container 2B can be prevented from being inclined with respect to the moving direction M, and can be discharged in a predetermined posture. It is placed on the paper tray unit 255.

Next, as an inspection process, the imaging unit 261 and the barcode reader 262 of the inspection unit 260 inspect whether the printed character information such as the lot number and the barcode variable information area 2R are in a predetermined state. To do. At this time, since the paper container 2B is placed on the paper discharge tray unit 255 in a predetermined posture by the guide unit 254, during the inspection process by the imaging unit 261 and the barcode reader 262 of the inspection unit 260, the variable information area 2R is stored. Reading can be performed reliably. Therefore, when reading is impossible, it can be seen that the variable information area 2R is not printed in a predetermined state. Further, the paper mechanism 2B that has been ejected by the ejection mechanism 250 does not deviate from a predetermined position by pressing the already-printed paper container 2B. Therefore, in the paper container 2B discharged to the paper discharge tray unit 255 after the printing is finished, the variable information area 2R whose print contents change is overlapped on the paper discharge tray unit 255 in a predetermined order, and the order is shifted. There is nothing.

According to the paper container manufacturing method of the present embodiment, after printing of the variable information area 2R is completed, the posture is controlled by the posture control unit 252 of the guide unit 254, and is supported by the support pieces 253 and 253 of the guide unit 254. At the same time, the paper container 2B is discharged to the paper discharge tray section 255. As a result, the paper container supported by the support section 253 does not come into contact with the paper container 2B placed on the paper discharge tray section 255. Therefore, the paper containers 2B placed on the paper discharge tray section 255 are not pushed away, and the paper containers 2B can be successively placed on the paper discharge tray section 255 in the same stacking order as the order of printing the variable information. .

According to the paper container manufacturing method of the present embodiment, after printing of the variable information area 2R is completed, the posture is controlled by the posture control unit 252 of the guide unit 254, and is supported by the support pieces 253 and 253 of the guide unit 254. At the same time, the paper container 2B is discharged to the paper discharge tray section 255. For this reason, the central portion of the paper container 2B in the width direction V is lowered by its own weight, and the cross section in the width direction of the paper container 2B becomes a substantially arcuate convex shape and moves on the support portion 253. Does not hang down. Therefore, the paper container (processed paper container) 2 </ b> B supported and moved by the support unit 253 does not come into contact with the paper container 2 </ b> B already placed on the paper discharge tray unit 255. As a result, the paper container 2B already placed on the paper discharge tray unit 255 does not move, and the placement position on the paper discharge tray unit 255 does not move.

Therefore, it becomes possible to easily manufacture the variable information area 2R corresponding to the various types of small lots in a state where the paper containers 2B printed on the surface are stacked in the order corresponding to the variable information to be changed. At the same time, the paper container 2B discharged by the discharge mechanism 250 can be accurately placed on the paper discharge tray section 255 at a predetermined position defined by the support section 253, so that variable information is read correctly from the discharged paper container 2B. Therefore, the inspection unit 260 can inspect as it is.

Hereinafter, a paper container manufacturing apparatus according to a third embodiment of the present invention will be described with reference to the drawings.

In the present embodiment, as shown in FIG. 14A, in the fixed information printing step, first, a predetermined material sheet as a sheet is prepared, and a design area (fixed information area) 2D is printed on the material sheet. The necessary bending lines 2B2, 2B5, etc. are engraved. Thereafter, the paper container on which the design region 2D is printed is punched into a predetermined contour shape and die-cut to obtain a paper container 2B0 in a blank state as shown in FIG. 14A. Next, as shown in FIG. 14B, the paper container 2B0 is folded according to the folding line 2B5, and then an adhesive is applied to the margin part 2B3. After that, as shown in FIG. 14C, a paper container (sack-attached paper container) 2B formed in a cylindrical shape by bending according to the fold line 2B2 and pasting the paste margin part 2B3 and the side plate end part 2B4 is formed. obtain.
In the paper container manufacturing apparatus 210, the sack pasted paper container 2 </ b> B is stocked in the sack paster supply unit 211.
The variable information is printed on the paper container 2B as a variable information printing step, and is discharged to the paper discharge tray by the discharge mechanism 250.

Also in this embodiment, there can exist an effect equivalent to 2nd Embodiment mentioned above.
In addition, the fixed information area 2D printed in advance can be printed on the paper container 2B with the variable information area 2R sack pasted with high positional accuracy. It becomes possible to supply the paper container 2B.
In the present embodiment, the fold line 2B5 can be moved in the moving direction M with the fold line 2B5 as the front side, but the fold line 2B5 can also be moved in parallel with the moving direction M.
